OS X window drawing gem

ruby-talk

Hi,

Not a ruby question as such (sorry), but one of you might know.. Is there
a ruby gem that lets me open an OS X window, blit pixels to it, and handle
basic, mouse input?

Seems like someone must have wanted to do this before?

I'd really rather not have to import the whole of OpenGL just to display a
2d bitmap in a window.

Thanks,

It's still rough, but you might like my graphics gem:

The code lives here:

and lets you do things like:

class Ball < Graphics::Body
  def initialize w
    super

    # ...
  end

  def draw
    w.angle x, y, a, 10+3*m, :red
    w.circle x, y, 5, :white, :filled
  end

  def update
    fall
    move
    bounce
  end

  # ...
end

class BounceSimulation < Graphics::Simulation
  attr_accessor :bs

  def initialize
    super 640, 640, 16, "Bounce"

    self.bs = populate Ball
  end

  def update n
    bs.each(&:update)
  end

  def draw n
    clear
    bs.each(&:draw)
    fps n
  end

  # ...
end

BounceSimulation.new.run
